The small-sized circumferential welding system is used for welding vessel diameter less than φ1000mm. It is composed by headstock, tailstock, hydraulic pump, beam, pneumatic bracket, welding trolley, slider, arc protection cover, and controller, etc. The work piece is clamped by adjustable chuck on the headstock;  and it can be adjusted to coaxial with the main spindle by means of the ruler on the chuck. The tailstock clamps the work piece by hydraulic pump; When necessary, it can use pneumatic support in the middle of work piece.
